Unfortunately she wasn't after kites. :( So on Sunday morning she woke me far earlier than anyone without kids would ever wake up to ask for my help. The diagrams I sent her were not quite this nice (since I had just woken up), but they were along the same lines.
For my samples I started with 5" x 3" rectangles and ended up with 4.25" x 3.5" rectangles. Here are some layouts I was playing with. The aren't as versatile as HSTs, but I think they could make a cool design.
